This patch series introduces a driver for Samsung S6E8AA5X01, which is
an AMOLED MIPI DSI panel controller. This panel is found in several
(mostly Samsung) phones, in at least two different sizes - 720x1280 and
720x1480.

Changes in v3:
- added brightness values for upto 500 nits.
- removed unused mutex object from panel code.
- Link to v2: https://lore.kernel.org/r/20250625-panel-samsung-s6e8aa5x01-v2-0-4db72b87a5a4@disroot.org
Changes in v2:
- fixed various dt_binding_check errors (conor)
- simplified panel enable sequencing (tzimmermann)
- did s/s6e8aa5x01_update_brightness/s6e8aa5x01_update_status (tzimmermann)
- added check for panel enable in s6e8aa5x01_update_status() (tzimmermann)
- used backlight_get_brightness() in appropriate places (tzimmermann)
- Link to v1: https://lore.kernel.org/r/20250612-panel-samsung-s6e8aa5x01-v1-0-06dcba071ea6@disroot.org

Samsung S6E8AA5X01 is an AMOLED MIPI DSI panel controller. Document the
compatible and devicetree properties of this panel driver. Timings are
provided through the devicetree node as panels are available in
different sizes.

Samsung S6E8AA5X01 is an AMOLED MIPI DSI panel controller. Implement
a basic panel driver for such panels.
The driver also initializes a backlight device, which works by changing
the panel's gamma values and aid brightness levels appropriately, with
the help of look-up tables acquired from downstream kernel sources.

The panel dimensions is the only thing which differs. The model name,
controller, registers, and functionality are supposedly all similar, so
I believe this is fine...

If only the dimensions change, then width-mm and height-mm would be enough, right?

I'd say, it is typical to have a controller to be used by different
panels. However usually those panels have different names or IDs. Please
follow the typical way of handling such a situation and use panel IDs
for compatibles.
